Abstract
Description
Technical Field
[0001] This utility model relates to the field of barnacle removal technology on ship hulls, and more specifically, to a barnacle removal robot for ship hulls using an electrocatalytic nanobubble synergistic biomimetic brush. Background Technology
[0002] During long voyages, ships are highly susceptible to fouling and adhesion from marine organisms, with barnacles being one of the most common and difficult to remove. Barnacles adhere firmly to the hull coating by secreting highly adhesive proteins, forming a hard calcareous shell. This not only significantly increases surface roughness, leading to increased drag and fuel consumption, but also accelerates corrosion of the hull's metal structure, severely impacting operational efficiency and service life. Therefore, regular hull cleaning to remove marine fouling organisms, including barnacles, is a crucial maintenance measure for ensuring ship performance and reducing operating costs.
[0003] Most existing underwater cleaning robots use rotating brush heads or high-pressure water jets for physical removal. However, for firmly attached organisms like barnacles, simple physical removal requires applying considerable force, which can easily damage the antifouling coating on the hull. Utility Model Content

It solves the problem that many existing underwater cleaning robots rely on rotating brush heads or high-pressure water jets for physical removal. However, for firmly attached organisms like barnacles, simple physical removal requires significant force, which can easily damage the antifouling coating on the hull.

Detailed Implementation
[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0015] Please see Figures 1-4 This embodiment provides a barnacle removal robot for a ship's hull using electrocatalytic nanobubbles in conjunction with a biomimetic brush. The robot includes a shell 1, in which a waterproof cylinder 2 is fixedly installed. A disc 3 is fixedly connected to the telescopic end of the waterproof cylinder 2. An installation cavity is formed in the disc 3, and a biomimetic brush block 4 is rotatably connected to the inner wall of the installation cavity. A circular opening is formed on the lower end face of the disc 3, through which the lower end of the biomimetic brush block 4 passes. Multiple biomimetic bristles 401, made of silicone, are provided on the lower end face of the biomimetic brush block 4. An electrocatalytic nanobubble generating module 5 is also provided on the lower end face of the disc 3, and the electrocatalytic nanobubble generating module 5 includes at least one pair of electrodes. The electrode is electrically connected to a high-frequency pulse power supply located inside the robot housing 1. The mounting cavity is equipped with a rotating component 6, which drives the bionic brush block 4 and the bionic brush bristles 401 to rotate. The rotating component 6 includes a waterproof geared motor 601 fixedly mounted on the inner wall of the mounting cavity. The output end of the waterproof geared motor 601 is fixedly connected to a rotating rod 602. A gear 603 is fixedly sleeved on the rotating rod 602. The gear 603 meshes with a toothed ring 604, which is fixedly sleeved on the bionic brush block 4. The robot housing 1 is equipped with a magnetic adsorption walking mechanism 8, which is used for the robot housing 1 to crawl and adsorb on the surface of the ship.
[0016] In summary, the improvement of this embodiment lies in: Nanobubbles are generated by the electrocatalytic nanobubble generating module 5 to soften the attachment structure of barnacles and reduce their adhesion. Combined with the rotating bionic bristles 401 for physical removal, the two work together to significantly improve the removal efficiency. The bionic bristles 401 are made of silicone, which is soft and elastic. They can remove barnacles without scratching or corroding the hull coating or metal surface, thus extending the life of the hull.
[0017] Based on the above, other structures also need to be disclosed in detail, such as: Please see Figure 1 and Figure 2The magnetic adsorption walking mechanism 8 includes four walking wheels 801 symmetrically arranged on the robot housing 1. A walking track 802 is fitted on two corresponding walking wheels 801. The walking track 802 is composed of magnetic blocks. The walking track 802 composed of magnetic blocks provides a strong adsorption force, enabling the robot to crawl stably on vertical or even inverted ship surfaces.
[0018] Please see Figure 1 and Figure 2 A mounting plate 9 is fixedly connected to the robot shell 1. A waterproof camera 901 is installed on the mounting plate 9. The waterproof camera 901 provides real-time images to assist the operator in accurate positioning and status monitoring.
[0019] Please see Figure 1 The robot housing 1 is equipped with a navigation and positioning module 10 of model TDK InvenSense ICM-20948 and a communication module 11 of model Develotic HAM-Node. The navigation and positioning module 10 and the communication module 11 receive instructions and guide the robot to the barnacle attachment area.
[0020] Please see Figure 2 Multiple limiting telescopic rods 7 are symmetrically fixedly connected in the robot housing 1. The telescopic end of each limiting telescopic rod 7 is fixedly connected to the upper surface of the disc 3. The limiting telescopic rods 7 ensure the smoothness and precision of the pressing process.
[0021] In summary, the working principle of this solution is as follows: The robot is firmly attached to the hull surface via its magnetic adsorption walking mechanism 8. The walking tracks 802, composed of magnetic blocks, provide strong adhesion, enabling the robot to crawl stably on vertical or even inverted hull surfaces. The navigation and positioning module 10 and communication module 11 receive commands and guide the robot to the barnacle attachment area. A waterproof camera 901 provides real-time video feeds to assist the operator in precise positioning and status monitoring. Once the robot reaches the work site, the electrocatalytic nanobubble generating module 5... First, the electrode pair integrated on the lower end face of disk 3 is driven by a high-frequency pulse power supply to electrocatalytically electrolyze the surrounding water, generating a large number of micron / nano-sized bubbles. These bubbles are characterized by their small size, large specific surface area, and long surface life, enabling them to quickly penetrate and accumulate at the adhesion interface between the bottom of the barnacle and the hull coating. The nanobubbles at the interface create a "cushion" effect, physically expanding and weakening the adhesion of the barnacle. Under a high-frequency electric field, the collapse of the nanobubbles (cavitation effect) generates microjets and local high pressure, impacting the adhesion. The electrocatalytic process changes the chemical environment at the interface, further decomposing the sticky substances secreted by the barnacle, thereby significantly reducing its adhesion. After the electrocatalytic module has been working for a period of time and the barnacle attachment structure has been sufficiently softened, the mechanical cleaning system begins to work in conjunction. The waterproof cylinder 2 actuates, its telescopic end extends downward, driving the entire disc 3 and the bionic brush block 4 and bionic bristles 401 below it to move towards the hull surface until the bionic bristles 401 are fully in contact with the barnacle surface. The limiting telescopic rod 7 ensures the smoothness and precision of the downward pressing process. At the same time, the rotating component 6 starts working, the waterproof geared motor 601 starts, and through the meshing transmission of gear 603 and gear ring 604, it drives the bionic brush block 4 and the bionic bristles 401 on it. Rotating at a constant speed, the biomimetic brush 401, made of silicone, combines flexibility with sufficient cleaning power. During rotation, it can gently and thoroughly scrape away barnacles softened by nanobubbles from the hull surface, while avoiding damage to the antifouling paint or metal substrate caused by hard bristles. Throughout the cleaning process, the generation of electrocatalytic nanobubbles and the rotation and scrubbing of the biomimetic brush 401 can occur simultaneously or alternately, forming a synergistic enhancement effect. The nanobubbles "open the way" at the front end to soften the barnacles, and the biomimetic brush follows closely to remove them. The two work together to achieve a highly efficient and non-destructive operation mode of "softening first and then removing". The removed dirt is washed away by the water flow, and the robot then moves to the next work point under the drive of the magnetic adsorption walking mechanism, repeating the above process until the cleaning task of the entire designated area of the hull is completed.
